I should have done a comparison to original Clojure first. In Clojure, rand-nth on an empty vector does throw an exception, as Meikel says. As does any use of nth with a bad index and no not-found parameter. So that seems to be a bug.
But, nth on a set never works in Clojure, throwing "java.lang.UnsupportedOperationException: nth not supported on this type: PersistentHashSet". So, the fact that it works at all in Clojurescript seems to be a bug as well. On Aug 15, 1:13 am, "Meikel Brandmeyer (kotarak)" <m...@kotka.de> wrote: > Hi, > > Am Sonntag, 14.
